<h3 id="rationale">Rationale:</h3>
<p>A word that looks like a redirection in simple shell commands causes
it to be interpreted as a redirection. ShellCheck would guess that you
don't want it in tests.</p>
<h3 id="exceptions">Exceptions:</h3>
<p>When it's among a continuous list of redirections at the end of a
simple <code>test</code> command, it's more likely that the user really
meant to do a redirection. Or any other case that you mean to do
that.</p>
